Sequence-of-returns risk is the danger that bad market years occur early in retirement when withdrawals compound losses, making recovery impossible. A retiree experiencing a 30% market decline in year 1 + the 4% withdrawal effectively loses 34% of their starting portfolio — and never recovers. The gilt ladder mitigation: hold 2-5 years of spending in short-to-medium-dated gilts. When markets fall, withdraw from the gilt ladder instead of selling equity at lows. This buys 24-60 months for markets to recover. The "size" of your ladder depends on your tolerance for downside scenarios — 2 years is minimum, 5 years is conservative.
The sequence-risk problem demonstrated
Two hypothetical retirees, both start with £500k, withdraw £20k/year (4%), same long-run 7% annualised return:
| Year | Retiree A: bad early, good late | Retiree B: good early, bad late |
|---|---|---|
| 1 | −25% | +25% |
| 2 | −15% | +15% |
| 3 | +25% | −10% |
| 4 | +12% | +12% |
| 5-25 | +7% average | +7% average |
| 26-30 | +12% average (good late) | −15% average (bad late) |
| Outcome at year 30 | Portfolio depleted by year 18 | Portfolio £400k+ |
Same average annual return. Same withdrawals. Wildly different outcomes. The difference: Retiree A withdrew from a falling portfolio in years 1-2, locking in losses they couldn't recover from.
Why this is worse for retirees than accumulators
An accumulator (working person) experiencing a market crash in year 1 of 30-year saving:
- Loses 30% of current portfolio.
- Continues earning, contributing, buying at discount prices.
- Recovery is automatic via 29 more years of contributions.
A retiree experiencing the same crash:
- Loses 30% of current portfolio.
- Withdraws income, compounding the loss.
- No new contributions — recovery requires growth from a reduced base.
Same crash, very different outcomes. This is why retirement is fundamentally different from accumulation.
The gilt ladder solution
Hold 2-5 years of spending in short-to-medium-dated UK gilts. When markets are healthy, withdraw from equity. When markets crash, withdraw from the gilt ladder. Buy time for markets to recover.
Mechanism for a 5-year gilt ladder, retiree with £20k/year spending:
| Rung | Gilt | Maturity | Funded with |
|---|---|---|---|
| Year 1 (this year) | Money market / short gilt | Immediate | £20,000 |
| Year 2 | TR25 (Treasury 0.25% 2025) | Jan 2025 | £20,000 |
| Year 3 | TR26 (Treasury 0.125% 2026) | Jan 2026 | £20,000 |
| Year 4 | TG27 (Treasury 0.25% 2027) | Jan 2027 | £20,000 |
| Year 5 | TG28 (Treasury 0.125% 2028) | Jan 2028 | £20,000 |
| Total gilt ladder buffer | £100,000 | ||
The rest (say £400k of a £500k portfolio) stays in growth assets: 70% equity, 30% global aggregate bond ETF.
How the ladder protects you in a market crash
Imagine year 1 of retirement. Markets crash 30%.
- Equity portion £400k × 70% = £280k → £196k (down £84k).
- Bond portion £400k × 30% = £120k → £108k (down £12k).
- Gilt ladder £100k → still £100k (gilts unaffected by equity crash).
Year 1 withdrawal: £20k FROM THE GILT LADDER, not from equity. The crashed equity has 5 years to recover before you need to sell any.
By year 5, if markets have recovered, sell equity at higher prices to rebuild the ladder. If markets haven't recovered, you have another year of buffer — and historical data shows 5-year periods of negative real equity returns are very rare.
Sizing the gilt ladder — how much buffer?
| Ladder size | Coverage | Trade-off |
|---|---|---|
| 1-2 years | Brief market dips only | Minimum buffer; capital deployed for growth |
| 3 years | Most normal recessions | Balanced approach for moderately risk-averse |
| 5 years | Severe recessions / multi-year bear markets | Standard recommendation; some growth opportunity cost |
| 7+ years | Extreme cases (1929-style crash + slow recovery) | Conservative; meaningful opportunity cost |
For most UK retirees aged 55-70, 3-5 years of spending in gilt ladder is the standard balance between growth potential and sequence-risk protection.
Rebuilding the ladder annually
At the end of each year:
- One gilt matures → £20k cash for next year's spending.
- If equity is up: sell £20k of equity, buy a new 5-year gilt to extend the ladder.
- If equity is down: don't sell equity. The ladder shortens to 4 rungs but you have another year of recovery time.
- If equity is up next year: rebuild the long end of the ladder.
This adaptive rebalancing means you sell equity at high prices and avoid selling at low prices — exactly what an unstructured retiree fails to do.
The tax angle for higher-rate retirees
For a higher-rate retiree outside ISA/SIPP, the gilt ladder has a tax efficiency angle:
- Low-coupon gilts have most return as capital gain — CGT-EXEMPT.
- Coupons are taxed but small.
- vs Cash savings: interest taxed at 40% above PSA.
For a higher-rate retiree with £100k gilt ladder in a GIA, the tax savings vs taxable cash savings over 5 years can be £4-8k.
Alternative ladder structures
- Cash + short-dated gilts: simpler but less tax-efficient.
- Money market fund + 1-2 year gilts: ultra-conservative.
- Index-linked gilts: for inflation protection. Real yields are lower; useful if very long horizon.
- Annuity + smaller equity portfolio: partial annuitisation eliminates sequence risk on the annuity portion. See the annuity vs drawdown guide.
